A Valley Center man was killed in a crash Monday night in Kearny Mesa, the California Highway Patrol (CHP) confirmed.
The crash occurred at 8:06 p.m. on westbound State Route 52 near Convoy Street. All lanes were shutdown for at least an hour.
According to CHP, a 2009 Harley Davidson motorcycle rear-ended a Honda Civic at more than 70 miles per hour. The motorcycle was carrying two people - a male driver and a female passenger, CHP officials said.
The driver of the Honda, who didn't identify himself, said he heard two loud booms before he was pushed onto the shoulder of the freeway.
The impact of the collision sent two people on the motorcycle flying off.
Investigators said when a 2011 Hyundai Sonata ran over the motorcycle, the bike burst into flames.
An EMT who was driving by the collision stopped and attempted CPR on the motorcycle driver. The man was pronounced dead at the scene.
The female passenger was taken to Scripps Memorial Hospital in La Jolla.
CHP officials say it doesn't appear anyone was driving under the influence and no citations were issued.
All lanes of SR-52 were reopened within two hours of the collision.
